<p class="MsoNormal"><span style="font-size: 10pt; font-family: Arial;">We are
trying to determine the best way to reduce the metal artifacts in CT Data
acquired using GE/TOSHIBA scanner. </span></p>

<p class="MsoNormal"><span style="font-size: 10pt; font-family: Arial;">Based on
the literature there are two approaches either post processing or processing
during the reconstruction. We can only do the post processing of data at this
stage. </span></p>

<p class="MsoNormal"><span style="font-size: 10pt; font-family: Arial;">I have
already tried with Mean Filter and Gaussian Smoothing filter however the
streaking artifacts are spread over a wide region and this ends up blurring the
image. </span></p>

<p class="MsoNormal"><span style="font-size: 10pt; font-family: Arial;">Would you
have any suggestions? </span></p>

<p class="MsoNormal"><span style="font-size: 10pt; font-family: Arial;">The ROI is
lung tissue of a rabbit and the intensity values are required for
quantification. We are looking for intensity values close to air however, due
to the scatter effects we are not clear about the correct value. </span></p>
